or skirt portion thereof, adapted to the effectual sealing of glasstumblers, jars and other containers, said cap being constructed to be held on the container by the compression of the gasket against the. exterior surfaces of the container and thefrictional engagement of portions of the said flange or skirt with said exterior surfaces. One purpose of the invention is to provide a cap and gasket readily capable of being effectually sealed against plain exterior surfaces of a container, such as a glass tumbler, even though said surfaces may be tapered as dlstinguished from being verticah ln carrying out our inventlon we,provide a metalcap'adapted to pass downwardly over the upper and of a container and having a depending flange or skirt portion which is specially shaped, beaded or grooved to receive a packing ring or gasket initially not conforming to the shape of the groove but to be deformed and compressed therein upon and during the application of the cap to the container, and 1n accordance with our invention the flange or skirt portion of the cap is of suchconstructlon that upon the application of the cap and gasket to the container, the gasket may efi'ect'the sealing and said flange or skirt port on firmly and frictionally engage the ext-erlor surface of the container below said asket. We provide two means for securmg t e cap upon the container, one being the compressibility of the asket and the other the features of the ange or skirt portion of the cap below the gasket for engaging the exterior surfaces of the container, and these two means cooperat with the gasket affording an important auxiliary to the other means to prevent accidental dlsplacementof the cap under variations in the exterior surfaces of the container.

The inventionv will be fully understood from the detailed description hereinafter presented, reference being had to the accompanying drawings, in which:

' Figure 1 is a side elevation, partly in section, of a container, with the cap or closure of our invention superposed over the same and ready to be applied thereto, said closure being shown in central vertical section;

Fig. 2 is a central vertical section through the upper portion of a container and the closure of our invention, said closure being shown as having been pressed downwardly upon and sealing the container, and the gasket being shown as having been deformed by its engagement with the exterior surfaces of the container;

Fig. 3 is a side elevation, on a smaller scale, of the upper portion of a container sealed with the closure of our invention;

Fig. 4 is a like view showing a modification in the construction of the flange or skirt portion of the cap;

Fig. 5 is a vertical section on a larger scale, through a portion of the same, taken on the dotted line 5-5 of Fig. 4c;

. Fig. 6 is a view corresponding with Fig. 4, but indicating a further modified construction of the flange or skirt portion of the cap, and

F ig.7 is a vertical section, on a larger scale, through the same, taken on the'dotted line 77 of Fig. 6.

In the drawings, referring to Figs, 1, 2 and 3, 10 designates a container, which may be a glass tumbler, 11 the contents thereof, 12 the cap, 13 a downwardly depending flange or skirt constituting a portion of said cap, 14 an annular inwardly beaded or grooved section of said flange or skirt whose inner convex portion is adapted to engage the exterior surface of the container, 15 an upper'outwardly beaded or grooved section of said flange or skirt, and 16 a gasket of any suitable compressible material adapted to said section 15 and normally extending inwardly on acircle less in diameter than the exterior diameter of the upper end of the container, so that upon the application of the cap to the container the container acting against said gasket may compress the same within said section 15 and cause said gasket in compressed condition to closely bind against the upper exterior surface of the container. The beaded section 15 stands outwardly beyond the vertical plane of the sides of the tumbler 10 and curves downwardly and outwardly from the fiat top of I the cap 12, commencing outwardly from the :lip around the mouth of the tumbler, and,

then curves inwardly and merges into the inmetal cling against the exterior surface of '15 .the container, so as to afford a frictional wardly and then outwardl curved or beaded gripping section 14 the sk1rt'13.

The annular-inwardly beaded section 14. of the flange or skirt of the cap will normally be slightly less in horizontal diameter than the external diameter of the upper edge of the container 10, so that upon the application of the cap to the container, said section 14 will be forced outwardly to a limited extent and by the're'siliency of the or binding engagement of the flange or skirt 13 against said container. We preferably form the upper exterior portions of the container with vertical sides 17 so as to assure the firm engagementof the beaded section .-14 ofthe cap withsaid container when the cap is in position thereupon; The engagement of the beaded section 14 with the con-.

tainer does not prove entirely. effectual for sealing the container, because in many instances containers although intended to be accurate are irregular. or tapered around their upper portions and in addition the upper dges of glass "containers have certain irregularities and very fine grooves due to natural conditions "in. the production of the v containers, andthese"irregularities-and fine grooves, sometimes hard y. perceptible to the eye, prevent a' metal cap alone from sealing in an air-tight manner the container. In accordance with'our invention we rely for the sealing of the container, on the out- Wardly-beaded section 15 of the cap andthe gasket 16 therein-to be compressed against the exterior surfaces of the container adjacent to the upper edges .thereof,where irregularities and fine grooves are present in many glass containers as at present manufacturedw The headed section 15 extends outwardly beyond the inwardly beaded section 14, and within said beaded section/"15 v we apply the gasket' 16 which normally, as shown in Fig. 1, does not completely'fill the groove within said section. 15, but stands therein at an angle and has, parallel fiat inner and outer surfaces, a flat upper edge and a tapered lower edge 18 which normally projects inwardly on a diameter which is less than the external diameter of the upper end of the container 10', .so that upon the application of thecap and gasket to the container, the upper outer edge portions of the container will engage said tapered edge 18 ofthe gasketand force said gasket outwardly, with compressible effect, into the groove of the beaded section 15 of the cap, the result being that as the cap is continued on its downward movement upon the container, .the gasket 16 becomes greatly deformed and compressed and fills the groove of the beaded section 15 of the cap and very firmly engages the exterior surfaces of the upper edge portions of the container 10, as

The gasket 16 normally does not fit the groove of the beaded section 15 of-the cap,

but is placed at an angle,- therein so that quite a 'substantialportion ;of the gasket stands inwardly beyonduthe outer upper -edges of the container, and'due to this the application of the cap to the container-results in the gasket being deformed ..out-

wardly to fill the groove in the section 15' of the cap and to be compressed along an adequate surface against the exterior upper edges of the container. The downward and outward beveling of thelower edge of the gasket 16, as'at18, assures the-proper outi ward compression of the gasket into thesec tion, 15 of the cap, so that the gasket does not become pressed upwardly against the top of the cap and over the upper edge of thecontainer, but outwardly into the beaded sectionv 15 and against theexterior upper surfaces of the container. The compression of the gasket 16 against the upper exterior surfaces of the container not only adapts the cap for containers which var in their upper edge portions, but coacts with the inwardly beaded section 14 in looking the cap upon the container. Our purpose isto secure an effectual seal so that thecontents of the container may be preserved, and this result may be accomplished with entire sat isfaction with the presence of the gasket 16 within the upper beaded section 15 of the cap, and We believe said result cannot-be accomplished in "any satisfactory or universal manner with simply the engagement of the inwardly beaded section 14 with the exterior surfaces ofthe container. VVe .prefer 5 :tainer .10 have vertical surfaces 17, below which the container may be tapered, but we that the upper outer portions of the conare aware that the difficulties of 'manufacs turing the containers at reasonable expense and with the ordinary appliances frequently result in the section 17 not being truly verticahbut somewhat tapered, and in all such instances the seal of the cap upon the container cannot be efi'ectual with the inwardly beaded section 14, but is effectual when said section 14 is supplemented with the beaded section 17 containing the gasket 16, especially when said gasket normally is of less diameter than the outer. diameter of the upper end of the container.

'iVithin the grooved section or beading 22 neseleae .is somewhat more extended in dimensions than the beaded section 15 of Figs. 1 and 2. The lower portions of the flange or skirt 21 are inclined inwardly, as at 23, and then flanged downwardly, as at 24:, the body of the flange 24 -being normally free of the exterior surface of the container 19, but having spring lips 25 slit and pressed inwardly therefrom. so as to engage and bind against the exterior surfaces of the container 19 when the cap 20 is pressed downwardly thereupon, said lips 25 then serving to aid in locking the cap upon the container.

of the cap 20, we place a gasket 26 wiich although larger is normally of the same shape as the gasket, 16 and then has a beveled lower edge corresponding with the edge 18 in Fig. 1 and ,normally on a smaller diameter than the exterior diameter of the upper edge of the container 19, so that upon theapplication of the cap to the container, said beveled lower edge of the gasket will be engaged by the upper edge of the container and the container, as the cap is forced downwardly thereupon will compress the gasket outwardly into the section 22'of the cap and effect the close binding of thegasket 26 against the inner surfaces of said section 22 and against the upper outer surfaces of the container 19, the result being the effectual hermetic sealing of the container. In the construction shown in Figs. 4 and 5 the gasket seals the upper end of the container regardless of the usual irregularities that are present in glass containers and in addition by its binding force against the .container serves to aid in looking the cap 20 in position and to cooperate, in looking said cap, with the frictional engagement of the lips 25 with the exterior surfaces of the container.

In Figs. 6 and 7 we illustrate a further modification of the invention, and in Figs. 6 and 7 the container is numbered 27, the cap 28 and the gasket 29. The cap 28 has a flange or skirt portion 30 which differs from the flange or skirt portion 21 of Figs.

4 and 5, merely in thefact that in lieu of forming in the lower flange portion thereof the spring lips 25 of Figs. 4 and 5, we merely indent said fiangeportion, as at 31, to form inwardly pro ect1ng lugs to frictionally engage the exterior surface of the container 27 when the cap 28 is pressed downwardly thereupon. The gasket 29 of Figs. 6 and 7 is' the same as the gasket of Figs/4: and 5, and in view of the small difference between the structures shown in Figs. 4, 5 and 6, 7-, it is thought that ex tended explanation as to the modification presented in Figs. 6 and 7 will not be re-' quired. v

In all of the constructions shown we em ploy a cap having a flange or skirt portion possessing in a part thereof, means for resiliently engaging the exteriorsurface of the container, and in each instance the flange has an upper peripheral outwardly beaded section containing a gasket which normally, at its lower edges, is less in diameter than the diameter of the upper outer edges of the container, so that upon the application of the closure to the container the gasket is compressed outwardly to fill said beaded section and also becomes very firmly bound against the upper exterior edge portions of the container, said gasket thus not only creating an effectual outer seal, but cooperating with the lower or resilient portions of the flange in locking the cap on the container. In all the constructions shown the container has about its upper end, the usual smooth plain substantially vertical exterior surfaces commonly possessed by tumblers employed for holding food products, and in all said constructions the upper end of the tumbler passes through the gasket, with the result that the cap seats on the upper edge of the tumbler and the gasket affords an efli-. cient side-seal, while at the same time aid ing materially in securing the cap on the tumbler.
